BLUETTI SolarX 4K | World’s First 4kW Solar Charge Controller

BLUETTI SolarX 4K | World’s First 4kW Solar Charge Controller

The solar breakthrough that changes how you power everything.

Say hello to a world first. The BLUETTI SolarX 4K isn’t just another charge controller—it’s the planet’s first 4kW solar charge controller, engineered to squeeze every last watt out of your panels and pour it straight into your BLUETTI ecosystem.

Big Voltage In, Safe Power Out

Got a sprawling rooftop array? A ground-mounted setup? The SolarX 4K swallows anywhere from 150–500V and intelligently converts it into safe, sub-60V charging—delivering up to a massive 4,000W to your BLUETTI power stations. Translation: faster charging, more stored energy, and rock-solid reliability whether you’re backing up the family home, powering a remote cabin, or growing your own backyard solar farm.

Start at 4kW. Scale to 12kW. Power Without Limits.

Your energy needs are yours alone—so why settle for one-size-fits-all? Run a single SolarX 4K to keep the daily essentials humming, or chain up to three units together for whole-home muscle that hits 12kW. Thanks to smart AC coupling, it plugs into your existing solar setup while leaving your BLUETTI’s DC input ports wide open for even more panels. More energy. Faster. Nothing tied down.

One Controller. Your Entire BLUETTI Lineup.

The SolarX 4K plays beautifully with a huge family of BLUETTI power stations and battery packs—Apex 300, AC300, AC500, B300K, B300, and B300S. Charging a single station? Juicing up several at once? Mixing and matching stations with batteries? It adapts to whatever combination you throw at it, delivering safe, efficient, flexible solar charging built around your system.

Total Control, From Anywhere on Earth

Keep your finger on the pulse from the palm of your hand. The BLUETTI app lets you monitor performance in real time, push firmware updates, and troubleshoot in an instant—so you’re always in command, whether you’re in the next room or the next time zone.
